FRANK BEN LANTERY, OF SOUTH EASTON, MASSACHUSETTS.

Application filed August 19, 1919.

T 0 all whom it may concern,

Be it known that l, FRANK B. LANTERY, a citizen of the United States,and a resident of South Easton, Massachusetts, (whose post-officeaddress is South Easton, Massachusett-s,) have invented an Improvementin Candy-l Vrapping Machines, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

My present invention relates to wrapping machines, and more particularlyto improvements in machines for wrapping paper on stick candy and thelike.

' Heretofore, stick candy has been generally wrapped by hand, as, due tothe difliculty of handling the material, and the relatively unskilledlabor employed in its manufacture, the resultant product is not uniform,varying considerably as regards diameter and length and it has beenfound impossible to devise a machine that would successfully operate. Tosuccessfully operate from a commercial standpoint, a wrapping machinefor this class of goods should be capable of wrapping the paper onsticks of varying length andfldiameter, and twist the ends of the paperwrapping to securely enclose the candy in the paper, both for thepurpose of preventing the paper from unrolling, and for the sake ofcleanliness. In my improved machine, I successfully meet theseconditions by mechanism that sheers ofi' the proper length of paper andfeeds the same to a device that simultaneously rotates the candy stickand wraps the paper thereon. At the completion of the wrapping,mechanism is brought into play to twist the ends of the paper on thecandy stick, and finally the wrapped stick is ejected from the machine.

An object of my invention therefore, is the provision of means forrolling a Strip of paper on a stick of candy or the like.

Another object is an improved means for twisting the ends of the paperwrapping to securely fasten the paper on the candy, and enclose thecandy in the wrapping. A further object is the provision of means forsevering an appropriate length. of paper for each operation of themachine.

A still further object is the provision of improved means forsimultaneously rotating a stick of candy or the like and wrapping aprotective covering" thereon.

A further object is the provision of means Specification of LettersPatent.

for removing the wrapped stick of candy from the machine.

Other objects and novel features and arrangements of parts will appearfrom time to time as the description of the invention progresses.

I In the accompanying drawings illustrating the preferred embodiment ofmy invenion,

1 is a plan view,

F 1g. 2 is a side elevation, partly in section, of a portion of themachine, showing the rollers and guides in position to receive a stickof candy,

Fig. 3 is a view, similar to Fig. 2, witha stick of candy in position tobe wrapped,

Fig. 4C is a front elevation, partly in section,

Fig. 5 and Figs. 6 and 7 are details of the end twisting means.

Referring to the drawings, 10 designates a base supported on front andrear legs 11 and 12 respectively. Rearward extensions 13 on the base 10provide aligned bearings for a transverse shaft 14, receiving power fromany suitable source, and on which is fastened a pulley 15.

Near the front of the base 10 and above the legs 11 are arranged shafts16 and 17, parallel to each other and to the shaft 14. Mounted on theshafts16 and 17 and spaced apart'from each other, are a plurality ofwheels or pulleys 18, the periphery of said wheels being grooved andequipped with rubber bands or tires 19,circular in cross section. Theshaft 17 is provided with wheels or pulleys 20, similar in number andarrangement to the wheels 18 on the 'shaft 16, each wheel 18 and 20being centrally located with respect to the opposite pair of wheels 20and 18 respectively. The distance between the shafts 16 and 17 is suchthat with a given diameter of wheel 18 and 20, said wheels define atransverse trough or path in which a stick of candy 100 may lie duringthe wrapping operation. The shafts 16 and 17 are provided, at one endthereof, with pulleys 21 and 22 respectively, and belts 23 and 24connect the pulleys 21 and 22 respectively with the driving pulley 15.This driving connection between the pulleys 21 and 22, and the pulley 15is such that the shafts 16 and 17 are both driven in the same direction,with the result that the stick of candy placed in the trough defined bythe. wheels 18 and 20, is rotated. Forward extensions 23 and 24 on thebase 10, are provided with upstanding members, but one of which. isshown, screwed or otherwise secured to the extensions 23 and 24 Fastenedto and extending between the up standing members is an inclined table26, the rear end of which terminates adjacent the trough defined by thewheels 18 and 26. At the extreme forward end and at each side of thetable 26 are side plates 27 and 28, said plates being secured to thetable by screws 29 passing through right-angled extensions 30 and 31 onthe front ends of the plates 27 and 28, respectively. The major portionof the side plates is left free, as clearly shown in Figs-2 and 3, and,the side plates being made of resilient material, as spring brass or thelike, the distance between the side plates may be increased ordiminished, depending on the length of the sticks of candy 100. It willbe noted, by reference to Figs. 1 and 2. that the passageway existsbetween the table 26 and the side plates 27 and 28, and through which astrip of wrapping paper 32 may be fed diagonally across the table andinto engagement with the wheels 18. An upward projection 33 on the rearend of the base 10 provides a bearing for a stub shaft 34, on which ismounted the forwardly extending arm 35, to the front end of which isfastened, by screws 36, or in any other suitable manner. a cutter 37which co-acts with an edge of the table 26 to form a cutting device forsevering suitable lengths from the strip 32 of wrapping paper. On thearm 35 near the rear end thereof, is pivotally attached the upper end ofa depending link 38, the lower end of which is pivotally attached to alink 88 fastened to a shaft 39 mounted in bear ing extensions 40 on therear side of the legs 11. Intermediate the ends of the link 88 ispivotally attached the upper end of a rod 41, which extends downwardlyto a treadle (not shown) and by means of which the link 88 and partsassociated therewith are operated.

Extending between the legs 12 and the members of the base 10 are rods 43and 42, which have attached to and support the rearwardly and downwardlyinclined table or runway 44. Botatably mounted on the shaft 17, neareach end. thereof, are crank arms 45, and extending between andfastened-to said crank arms is an extension 46 of the inclined table orrunway 44 and also a plurality of curved arms 47. The width of the arms47 is such that they fit between adjacent wheels 18 and 20, and thecurvature is equal to the radius of the stick of candy 100 to beoperated on. Pivotally attached to one of the crank arms is the lowerend of an upwardly extending link crank arms 54.

rareese 48, the upper end of which is provided with an elongated slot 49which engages with a pin 50 on the arm 35.

liotatably mounted on the shaft 14 at each end thereof, are bell cranklevers having long forwardly extending arms 51 and short upwardlyextending arms 52. At the forward ends of the arms 51 is rotatablymounted. a shaft 53 on which is mounted a plurality of wheels 54,similar in character to the wheels 18 and 20, said wheels 54 beingspacedapart on the shaft 53 and are equal in number to the total number ofwheels 18 and 20. A pulley 55 on one end of the shaft 53 is connected bya belt 56 to the pulley 15. Pins 57 in the arms 51 provide stops for theplate 58, pivotally mounted on the rod 59 extending between the arms,said plate 58 being provided with curved arms 60, similar in characterto the arms 47.

On the inner side of the legs 11 are plates 61 and 62 forming guidewaysin which slides a transverse plate 63, provided with vertical slots 64near each end thereof, in which slots work the ends 65 of the cam arms66 fastened to the shaft 39 at either end thereof. Intermediate the endsof the cam arms 66 are mounted the lower ends of links 67, the upperends of which are slotted at 68 to work on the rod 69 extending betweenand connecting the ends of the A pin 70 in each of the legs 1.1 limitsthe downward movement of the plate 63, while springs 71, fastened oneend to lugs 72 at each end of the plate 63 and the other end to the legs11. urge the plate 63 into its lowermost position. At each end of thetop of the plate 63 is fastened, by screws 73 or in any other suitablemanner, the upwardly extending forked twisting elements 74, (see Figs. 6and 7 The operation is as follows: with the devices in the positionshown in Fig. 3, a stick of candy 100 is rolled down the table 26, thetreadle (not shown) released, when the parts automatically come into theposition shown in Fig. 3, the stick of candy 100 being rotated in ananti-clockwise direction by the wheels 18, 20 and 54. The strip of paper32 is moved from left to right diagonally across the table 26 when thecorner thereof will be engaged by the wheels 18, 2t) and 54 and thewrapping operation beg ns. At this point, the treadle is depressedslightly, whereupon the link 38 pulls down the lever 35 to operate thecutter 37 and sever a length of paper from the strip 32. This downwardmovement of the lever 35 during the cutting operation does not affectthe remainder of the devices, because of the slotted connection betweenthe links 48 and 67 and their respective devices. The severed length ofpaper is wrapped around the stick of candy 100 and projects outward fromeach end thereof. The treadle is now still further depressed when theends 65 of the cam arms 66, engaging with the upper ends of the slots 64move the plate 63 and attached twisting devices 74 upward intoengagement with the projecting ends of the length of paper on the stickof candy 100, the stick of candy being meanwhile rotated by the wheels18, 20 and 54. Continued depression of the treadle causes the end of theslots 68 in the links 67 to engage with the rod 69 and rotate the crankarm 52, whereupon the long arm 51 moves the shaft 53 and wheels 54upward out of engagement with the stick of candy, causes pins 57 toengage with the plate 58 to move the curved arms 60 upwardly, and, bythe pin on the arm 35 engaging the bottom of the slot 49 in the link 48to cause a rotation of the arms 45 on the shaft 17, moving the plate 46downward and the curved arms 47 upward to throw the wrapped stick ofcandy 100 onto the inclined table and out of the machine. The abovedescribed sequence of operations may be repeated indefinitely.

I may, if desired, feed the paper strip automatically, though I havedescribed it as being fed by hand. Further, though I have described thepreferred embodiment of my invention somewhat in detail, it is to beunderstood that I may vary the details of the construction andarrangement of parts shown within comparatively wide limits withoutdeparting from the spirit of the in-- vention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. In a wrapping machine, the combination of an inclined table, yieldingguides mounted on each side of said table, a passageway between theguides and the table to permit the passage of a strip of papertherethrough, a cutting edge at one side of the table, and a pivotallymounted cutter cooperating with said cutting edge to sever the strip ofpaper passing between the guides and the table.

2. In a wrapping machine, the combination of a plurality of parallellyarranged shafts, a plurality of spaced wheels thereon defining a troughforv receiving a stick of candy or the like, an inclined table, overwhich the candy'is fed to the trough, a 1

second inclined table over which the candy is fed out of the machine, asupplementary table interposed between the second table and the trough,curved arms projecting from said supplementary table and lying normallybelow the trough and between the spaced wheels, and means for tiltingthe second table to throw the candy out of the trough onto the table.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.

FRANK BEN LANTERY.
